PUMP.

SPECIFICATION forming part of Letters Patent No. 223,631, dated A Application filed August 11, 1879.

. the packing to the main part of the plunger,

the points pressing into an annular recess in the bottom of the plunger; also, in the mode of securing the parts of the plunger and valve together.

Figure 1 shows an elevation of the pump and pipes. Fig.2 is a vertical cross-section of the plunger or bucket on an enlarged scale.

A is the cylinder of the pump,placed about six feet below the platform R. B is a pipe leading up from the pump through the platform, to convey the water and form a support for the working-lever e.

The body of the pump is made, preferably, of a glass cylinder held between two heads which are secured together by the rods S S.

The pipe 01 is of wood, and extends to the bottom of the well. It is connected to the pump by a short piece of enameled pipe, J. A small vent is made in thepump-cap at o, to relieve the pipe above of water when it is not in use.

G is a collar fitting loosely on the pipe B, and provided with one or more set-screws, v, to fasten it on the pipe. A flange on the lower edge of the collar has holes in it to receive fbolts, by which it is fastened down to the platorm.

A cap, L, is screwed onto the upper end of the pipe B, with a notch in it to hold the lever e. A small hole, 12, in this cap, into which a screw-plug is fitted, allows it to be used as an air-chamber, when the pump is used as a forcepump, by having the plug screwed in and when the pump is used as a lifting-pump, by leaving the plug out, the water is allowed to rise in the pipe above the outlet, and thus equalize the flow and prevent splashin My improvements in the plunger consist in making an annular recess in the bottom of the box N, and making points z a on'the top of the follower m, which press into the leather 1; in the recess and hold it securely. The follower m is secured to the box N by a T-bolt, l, on

one side, which also holds the valve a, down on its seat, and also by a countersunk screw-bolt, h, on the other side.

The piston-rod w, which is attached to the bail on the box N, passes through a stuflinga box in the top of the pump-cap, which is made with an oifset to receive the pipe B. This is for the purpose of bringing the axis of the cylinder A in a direct line with the point of connection on lever 0.

Having thus described my improvements, what I claim as my invention is-- i The combination of the box N, having a recess in its bottom, with the follower m, furnished with the points 22, valve to, and leather packing 11, all being heldtogether by "the T- boltl and the screw-bolt h, substantially as set forth.
